Black Majick must have bought all his stuff from 42 Draft Designs... I have the exact same thing. I have the hard plastic piping, picked amber instead of red LED's, etc... It's like a parallel gauge universe!

hahaha
Anyway, there is indeed plenty of room for everything. It's an easy dash to work in. I had some trouble poking through the grommet on the firewall. I poked the one where all the wires for the ECU come through. It's double-walled and thick. I poked a nail through it, then put some liquid soap on the vacuum hose, then put the hose on the nail and pushed the nail back out into the engine bay. ....or at least that's what I did after a few other things didn't work.
I also ran the signal wire for my oil pressure gauge through that grommet. Overall an easy installation, especially with the instructions from 42DD. They were fantastic to deal with.
I would recommend getting your gauges, panels, etc. from:

I dealt with Evan. I would email him first, tell him what you want to do, and then he'll tell you everything you need and the cheapest way to go about it. Great place!
BTW, Black Majick, how did you mount the gauge panel?
